MILKING DEVICE.

Specification of Letters Patent.

Patented Apr. 30, 1912.

Application filed February 3, 1912. Serial No. 675,223.-

To all whom it may concern:

Be it known that I, ELLTs LI WAY, residing at Ennis, in the county ofEllis and State of Texas, have invented certain new and usefulImprovements in Milking Devices, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a milking device, and my invention aims toprovide a portable device that can be easily moved from one cow toanother and milk extracted from the teats, without injury to the sameandwrthout any danger of the device becoming clogged by butter fat orother semisolid matter in the milk.

The invention further aims to provide a milking device that is easilyapplied to the ture and highly efficient for the purposes for p which itis intended.

The invention still further aims to accomplish the above results by acombination of mechanical elements that will be hereinafter specificallydescribed and then claimed, and reference will now be had to thedrawings, wherein A Figure 1 is a side elevation of a portion of thedevice, Fig. 2 is a perspective view of a portion of the device asapplied to the by a pin 8 connecting said bearings.

The tank 5 has a detachable air tight lid or cover 9, and associatedwith said tank is a suction pump 10 of a conventional form, said suctionpump having the piston rod 11 thereof connected to the fulcrumed lever 7by a pin 12 that extends through a 1ongitudinal slot 13 in said lever.The tank 5 at a point diametrically opposite the suction pump 10 isprovided with a connection l t to which is connected a hose 15 havingbranches 16. The, ends of the branches 16 terminate in nipples 17 thatare fitted upon the teats 18 of a cow.

The platform 4, at the forward end thereof, has a guidepost 19 and theupper end of the post is provided with spaced brackets 20 and 21, theformer having radially bifurcated arms 22 and the latter radial arms 23that have the ends thereof curved, as at 24 and provided withsemicylindrical stationary nipple members 25.

Slidably mounted upon the post 19 above the brackets 20 and 21 aresleeves 2(' and 27 connected by a yoke 28. The sleeves 26 and 27 areprovided withapertured ears 29 and pivotally connected to said cars bypins 30 are Y-shaped yokes 31 that are pivotally connected, as at 32 tomovable. semicylindrical nipple members 33.. The lower ends of themembers 33 are'provided with curved arms 34 that extend through thebifurcated endsof the arms 22 and the arms 34: have the ends thereofprovided with revoluble rollers 35 that engage under the arms andprevent the members 33 from shifting vertically when actuated.Encircling the post 19 between the sleeve 26 and the bracket 21 is acoiled compression spring 36 that retains the members 33 normallyretracted;

The forward end of the fulcrumed lever 7 is provided with a slotted yoke37 that is loosely connected by pins 38 to the sleeve 26.

To place thedevice in operation, the forward end of the truck is shiftedunder a cow and two of the nipples carried between the members 25 and 33and placed upon the teats, the tea-ts being lowered between saidmembers. The other two nipples are placed upon, the remaining teats tocollect such milk as may be discharged during the milking operation ofthe first mentioned teats. The fulcrumed lever is then rocked and thesleeves 26 and 27 raised and lowered upon the post 19, said movement ofthe sleeves causing the members 33 to move back and forth toward themembers 25, thereby pressing the nipples and the teats within saidnipples. During this operation the milk that enters the hose 15 is drawninto the tank 5 by the suction pump 10. After the device has been inoperation upon two of the teats, it is transferred to the other teatsand the operation repeated.

Vhat I claim is 1. A milking device comprising a tag/k, a guide postadapted to be positioned un er a cow, a hose connected to said tank andhaving branches, nipples carried by the branches of said hose andadapted to be placed upon the teats of a cow, stationary members carriedby said post and engaging said nipples, movable members associated withsaid stationary members and adapted to be moved to press said nipples,and means including yokes, sleeves and an operating lever for actuatingsaid movable members.

2. A milking device comprising a tank, a guide post adapted to bepositioned under a cow, a hose connected to said tank and havingbranches, nipples carried by the branches ofsaid hose and adapted to beplaced upon the teats of a cow, stationary members carried by said postand engaging said nipples, movable members associated with saidstationary members and adapted to be moved to press said nipples, meansin eluding yokes, sleeves and an operating lever for actuating saidmovable members,

and means associated with said tank and actuated by the lever of thefirst mentioned means for producing a suction in said hose.

3. A milking device comprising a tank, a guide post adapted to bepositioned under oaaeoa a cow, a hose connected to said tank and havingbranches, nipples carried by the branches of said hose and adapted to beplaced upon the teats of a cow, stationary members carried by said postand engaging said nipples, movable members associated with saidstationary members and adapted to. be moved to press said nipples,means'ineluding yokes, sleeves and an operating le In testimony whereofI afiix my signaturein the presence of two witnesses.
